I'm pretty sure there is, in the bios in boot settings, as far as i know, there is the option for uefi~[win8 etc] and legacy~[win7,vista,xp etc] and it can be switched between the two, have a look anyway.

Here are screenshots i dont see a legacy rom option in these windows..

Its all i see. I did update my asmedia drivers in windows but not the firmware.

it loads up and says .93 version of firmware.
I actually dont know how to update the firmware, I seen instructions but it was combining the firmware with a bios upload and modifying stuff.... not official i thought.

I have the same crosshair V mobo you have and you cannot disable uefi bios, you can however switch some things to run off there legacy rom includeing network chip, and the usb chipset(asmedia) but you cant revert to an earlier type of bios in anyway(ie non efi).

as for a bios update just download the latest one from rog onto a usb stick and you can update it through the bios screen on bootup

Well hope it all works out for you, i have the newer board the maximus gene v, hope asus responds to your request, when your board came out maybe win 8 was not yet on the horizon etc. I will have a look at the firmware you linked too, i always update everything i can usually lol.

I have windows 7 but i reserve that system for games that use more than 4 cores or DX10+.

So I'm dual booting. I like it this way. Why bloat my perfect windows 7 install with Need For Speed Underground 2, Call of Duty 2, or The Witcher 1, list goes on...
Guitar Hero is another game that doesnt even support windows 7... list goes on.

I'm not saying this stuff wont work in Windows 7,I just prefer it this way, its also not an easy transition plus I like the thought that my Windows XP which i paid several hundered dollars for a while back in ancient times isnt completely gone. Same reason why I'll keep Office 2003.

It would be alot of work switching 200+gigs of games alone not including programs onto windows 7. Windows 7 needs to be my fast OS. I dont want to bloat it. And i have both so theres no need.

Its funny in a way, I am suping my XP install with ramdisks, SSD cache... its all nice and all, kindof fun. My mobo supports XP which i specifically researched, and my video card supports as well. (7970)
